CLOSURE FOR POWDER-CANS.

To all whom it may concern:

Be it known that I, GEORGE 'W. CHILDs, acitizen of the United States,residing at Seeleyville, in the county of Vigo and State of Indiana,have invented new and useful Improvements in Closures for Powder-Cans,of which the following is a specification.

My invention relates to closures for powder cans and analogous devices;and it has for its object to provide a simple, inexpensive and eflicientclosure, susceptible of ready application to a can, and of use on anumber of cans in succession, and one adapted to serve the additionalfunction of a funnel and in that way facilitate the discharge of powderfrom the can.

\Vith the foregoing in view, the invention will be fully understood fromthe following description and claim when the same are read in connectionwith the drawings, accompanying and forming part of this specification,in which:

Figure l is a perspective view of a powder can equipped with the closureconstituting the best practical embodiment of my invention of which I amcognizant. Fig. 2 is an enlarged detail section, taken diametricallythrough the closure. Fig. 3 is a horizontal section taken in the planeindicated by the line 33 of Fig. 2, and showing the opening left in thehead of the can when the original closure means thereof is removed.

Similar letters designate corresponding parts in all of the views of thedrawings, referring to which:

A is a powder can having in its head a an opening 6 of the conventionalcharacter or of any other kind consonant with the purpose of myinvention. The wall of the opening 6 is shown in Fig. 8 as provided withequidistant, inwardly extending projections; the same being for theengagementof the original closure (not shown) of the can. Saidprojections, however, have nothing whatever to do with my invention, andthe opening 22 may, as before stated, be an opening such as shown or anopening of any other suitable character, without affecting my invention.

B is the tubular body or major-portion of my novel closure. The saidbody is preferably of metal, is flanged at c to bear on and rest snugagainst the can head, and is provided with an upper reduced portion dand an exterior shoulder e at the lower end of said reduced portion.

Specification of Letters Patent.

Application filed. October 14, 1908.

Serial No. 457,683.

In addition to the tubular body B, the closure comprises connectors C,and a removable cap D; the latter being of a size to snugly fit over andfrictionally engage the upper reduced portion cl of the body so as notto be liable to accidental displacement.

As shown in Fig. 2 the connectors C are in the form of spring stripswhich are preferably arranged diametrically opposite each other and areconnected at their upper ends to the body B, and provided at their lowerends with tapered heads f, the latter to pass through the opening Z) inthe can head a and assume positions immediately below said head with aview of holding the flanged base of the body B tightly down on the head.The connectors are also provided at intermediate points of their lengthwith finger-pieces E which extend radially outward through apertures gin body B and terminate in heads h.

As will be readily understood by reference to Fig. 2, the connectors Ctend to spring outwardly, and consequently serve to effect connection ofthe body B to the can head in such manner that there is no liability ofthe body being accidentally released during the use of the can. It willbe noticed, however, thatwhen the user of the device by pressinginwardly on the finger-pieces E moves the connectors C inwardlysufiiciently far for the heads f of the latter to clear the wall of theopening I), the closure device as a whole may be removed from the can.Also when the connectors are pressed inwardly and moved downwardlythrough the opening Z) and then released, they will immediately reassumethe positions shown in Fig. 2 and reelstablish the connection.

It will be gathered from the foregoing that my novel closure may be usedon a number of cans in succession; also, that when the capD is removedpowder may be poured through the tubular body B after the manner of afunnel. It will further be noted that a tight joint iseffected betweenthe can head and the body B and a similar joint between the body B andthe cap D, and consequently when the latter is in position on the bodythere is absolutely no liability of fire reaching the interior of thecan through the closure. From this it follows that my improved closureis adapted to fully meet mining regulations concerning the care ofpowder no matter how strict the latter may be.

As before stated the construction herein illustrated and describedconstitutes the best practical embodiment of my invention of which I amaware, but it is-obvious that in the future practice of the inventionsuch changes or modifications may be made as fairly fall within thescope of my claimed invention. 7

Having described my invention, what I claim and desire to secure byLetters-Pat'- ent, is:

The herein described closure for powder cans, comprising a tubular bodyhaving an outwardly extending horizontal flange at its lower end,adapted to bear on the head of a can, around an opening in said head, aremovable cap on the tubular body, resilient connectors fixedlyconnected at their upper ends to the inner side of the tubular body andextending through the lower end of the flan e b a s ace of a size tosmwl receive the head of the can, and finger-pieces fixed to andextending outwardly from the connectors, at intermediate points in thelength thereof, and also extending loosely through apertures in the wallof the tubular body.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
